Difficulties installing (possibly macOS specific)

[esnible]

I had a few problems with make install. Some of these problems I got past, some I haven't yet.

I'm using this work item to gather the problems before creating a pull with troubleshooting tips.

Problem: npm ERR! /bin/sh: cmake: command not found
Solution: brew install cmake

Problem: gyp: No Xcode or CLT version detected!
Solution: sudo xcode-select --reset
See this article for rationale.

Problem: npm ERR! ../cc/core/Size.h:1:10: fatal error: 'opencv2/core.hpp' file not found
Possible solution:

export OPENCV4NODEJS_DISABLE_AUTOBUILD=1
brew install opencv # this takes over an hour

After this I am getting similar C++ compilation problems, such as "node-gyp/18.9.0/include/node/v8-internal.h:646:38: error: no template named 'remove_cv_t' in namespace 'std'; did you mean 'remove_cv'?". It isn't clear to me if this means I have the wrong Xcode version for my Mac, the wrong Node.js version, the wrong Python version, or if cads requests the wrong opencv4nodejs or node-gyp version.

Currently the failure reports "gyp info using [email protected]", "gyp info using [email protected] | darwin | x64", and 'gyp info find Python using Python version 3.9.5 found at "/Users/snible/miniconda3/bin/python3"'.

I had intended to package CADS with a pre-built version of opencv. More work on that soon.

I'm on MacOS as well, and must not be having issues due to opencv already being installed on my system. I'll go back through my notes and make sure I'm not missing build steps in the readme.

I too am having problems installing on Linux. After some wrangling I was able to launch electron, but it complains about missing files, and none of the buttons work:

I also get this in the terminal while it's running:
libva error: vaGetDriverNameByIndex() failed with unknown libva error, driver_name = (null) [35652:0122/175826.995453:ERROR:gl_surface_presentation_helper.cc(260)] GetVSyncParametersIfAvailable() failed for 1 times!

PS I also had the "'opencv2/core.hpp' file not found" error, which seems to stem from the script looking for core.hpp in the wrong folder. Symlinking (ln -s /usr/local/include/opencv4/opencv2 /usr/local/include/opencv2) solved it.

Finally installed it, but it's not working. Same problem

Looks like we're overdue for a better process -- docker would probably work, as @esnible mentioned in #10.

Let me play around with a clean install and see where things are failing.

It's looking like some version mismatches in the node dependencies are causing opencv4nodejs to fail to build with newer versions of node & node-gyp. I'll see if I can't get that resolved.

Hi Zach!
Any news on how's the newer version coming along?
Thanks
